Mating and Parental Care in Lake Tanganyika's Cichlids

Cichlid fishes of Lake Tanganyika display a variety of mating and parental care behaviors, including polygamous and monogamous mouthbrooding and substrate breeding, cooperative breeding, as well as various alternative reproductive tactics such as sneaking and piracy. Moreover, reproductive behaviors sometimes vary within species both in space and in time. Here, I survey reports on mating and pa...

Acoustic Experience Shapes Alternative Mating Tactics and Reproductive Investment in Male Field Crickets

Developmental plasticity allows juvenile animals to assess environmental cues and adaptively shape behavioral and morphological traits to maximize fitness in their adult environment. Sexual signals are particularly conspicuous cues, making them likely candidates for mediating such responses. Plasticity in male reproductive traits is a common phenomenon, but empirical evidence for signal-mediate...

Alternative life histories in the Atlantic salmon: genetic covariances within the sneaker sexual tactic in males.

Alternative reproductive tactics are ubiquitous in many species. Tactic expression often depends on whether an individual's condition surpasses thresholds that are responsible for activating particular developmental pathways. Two central goals in understanding the evolution of reproductive tactics are quantifying the extent to which thresholds are explained by additive genetic effects, and desc...

Alternative reproductive tactics in fish

Among vertebrates, fish show by far the greatest variability of alternative reproductive tactics (ARTs). Usually, males attempting to monopolize access to females or fertilizations are parasitized by conspecific male competitors (Taborsky 1997). This is so common in fish (Mank and Avise 2006) that it appears to be the rule rather than the exception: in fish with external fertilization, 170 spec...

Alternative reproductive tactics and life history phenotypes

Alternative reproductive tactics (ARTs) coexisting within a population are found in many organisms. Their existence has been an enduring puzzle in evolutionary biology. Why should selection produce distinctly different alternatives to reach the same goal? How can such alternative solutions coexist in a population? What determines their evolutionary stability? Here we outline ultimate and proxim...
